Not able to pay Tesco credit card with curve

Hi all
New to this ,
I was trying to pay my Tesco credit card with curve either linked to my bank card and my Crypto.com card
When I went to enter my cvv number it gets stuck on a white screen when using curve,
Any suggestions
Thanks

Is ‘Curve Fronted’ enabled in your Curve app?

Yes I done it on and off,I tried my bank card direct and it worked
Just cannot pay it via curve
